Silly rule about European Court's carpeting (7)
I believe the answer is:
lecture
'carpeting' is the definition.
Although both the answer and definition are singular nouns, I cannot understand how they can define each other.
'silly rule about european court's' is the wordplay.
'silly' indicates an anagram.
'about' indicates putting letters inside.
'european' becomes 'E' (abbreviation e.g. EU).
'court' becomes 'ct' (abbreviation used in road names).
'rule' with letters rearranged gives 'lure'.
'e'+'ct'='ect'
'lure' placed around 'ect' is 'LECTURE'.
Can you help me to learn more?
(Other definitions for lecture that I've seen before include "Formal talk on a subject" , "Lengthy reprimand" , "Harangue" , "University teaching period" , "Discourse for students" .)
